Today new mixtures with significantly reduced insertion losses are under optimization and these materials start being competitive with other more conventional technologies (like pin or varactor
In this paper, we report a simple method to tune a finite HIS using varactor
In [5-9], tunable one stop-band filters are proposed based on varactor
loaded split ring resonators, RFMEMS metamaterials and DGS respectively.
According to current trends, RF-MEMS switches , PIN diodes , and varactor
diodes  are typically used to tune the operating frequencies of existing reconfigurable antennas.
In addition, the varactor
contribution is represented by a bias-dependent capacitance [C.
As the source of nonlinearity, the Schottky varactor
is employed for [C.
The HMC588LC4B Wideband HBT MMIC VCO incorporates the resonator, negative resistance device and varactor
Different novel intrinsic models are used to represent the Schottky, varactor
and PIN diodes included in the NLD library.
A limited number of electronically tunable HISs have been designed using solid-state varactor
The performance of the tripler designed in this work is comparable with the ones also designed with varistors, but apparently inferior to the tripler designed by varactor
, considering the output frequency of the varactor
tripler is about three times that of the varistor triplers.
In [11-14], it is proved that loading varactor
diodes to resonant antennas to demonstrate frequency agility has been widely employed.
1) can be the second order curve fitting for the diode characteristics or the MOS varactor
characteristics according to the sign of [alpha] and [beta].
